The equation y = 4.99x signifies a slope (m) of 4.99, indicating a cost increase of 4.99 units per additional item. The y-intercept (b) is 0, reflecting zero cost when there are no items.
In the equation y = 4.99x, where x represents the number of items and y represents the total cost, the equation is in the slope-intercept form, y = mx + b. In this form:
"m" is the slope of the line, and
"b" is the y-intercept.
For the given equation, y = 4.99x:
Slope (m): The coefficient of x is the slope. In this case, the slope (m) is 4.99.
Therefore, the slope of the line is 4.99. This means that for each additional item (x), the total cost (y) increases by 4.99 units.
Y-intercept (b): The y-intercept is the value of y when x is zero. In this case, since there is no constant term, the y-intercept (b) is zero.
Therefore, the y-intercept is 0. The absence of a constant term indicates that when there are zero items (x), the total cost (y) is also zero.
For the equation y = 4.99x:
Slope (m) = 4.99
Y-intercept (b) = 0
This implies that the total cost increases by 4.99 units for each additional item, and when there are no items, the total cost is zero.
